I have two of USAK's PV casual models (and fighting the urge to order the newly offered Welsh National tartan in casual!) I love them to death and wear them quite often. Heck, I even wore my Gunn casual with a tweedie argyll to a wedding over the weekend. I also have two wool kilts, with one on order. No, PV is certainly not the same as wool. If I were a rich man, I would have nothing but 13 and 16 oz wool. But, I'm not. So, I buy the next best thing to help fill my closet.
